Conventional electronic devices include a circuit board, a connector, and a module card (such as a wireless communication card). The connector is disposed on the circuit board. The module card is inserted into the connector to be coupled to the circuit board. The connector is commonly formed by plastic packaging. When the high-speed transmitted signal of the module card passes through the connector, this generates a high-frequency noise. The high-frequency noise may be received by the antenna of the electronic device, causing serious signal interference.
Additionally, the module card may need to be inserted into the connector at a particular insertion angle (for example, the M.2 card needs to be inserted into the connector at a tilted insertion angle). Therefore, it is difficult to provide a shielding structure which can sufficiently cover the connector, because the module card may collide with the shielding structure during insertion.

The shielding structure can sufficiently cover the connector, blocking the interference signal, and decreasing the amount of noise. The shielding structure of the embodiment of the invention includes the shielding cover and the shielding frame. When the user inserts the module card (such as M.2 module card) into the connector, the shielding cover can be removed from the shielding frame to prevent the shielding cover from being interfered with by the module card. After the module card is combined with the connector, the shielding cover can be rejoined with the shielding frame to provide a sufficient shielding effect. The shielding cover can be repeatedly combined with the shielding frame and detached from the shielding frame, and it is convenient for the user.
In one embodiment of the invention, the electronic device and be a wireless communication device. The module card can be a wireless communication card. The disclosure is not meant to restrict the invention.
Use of ordinal terms such as “first”, “second”, “third”, etc., in the claims to modify a claim element does not by itself connote any priority, precedence, or order of one claim element over another or the temporal order in which acts of a method are performed, but are used merely as labels to distinguish one claim element having a certain name from another element having the same name (but for use of the ordinal term).
While the invention has been described by way of example and in terms of the preferred embodiments, it should be understood that the invention is not limited to the disclosed embodiments. On the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
